Simulating a 2D acoustic (pressure) pulse in water with NumericalAI (https://numericalai.net/) 🌊🔊
A Gaussian source launches a short pressure wave and we track how it propagates across a 1 cm × 1 cm domain using high-order numerics (WENO/TENO). Results show clean pressure and x-velocity wave patterns over time.

This simulation visualizes a 3D supersonic bow shock forming around a sphere using NumericalAI (https://numericalai.net/). The simulation reproduces a stable, symmetric detached bow shock with realistic curvature and a developing wake downstream, making it an ideal reference case for validating compressible immersed boundary methods (IBM) and shock-capturing techniques.
